A high-severity security flaw has been disclosed in N-Able’s Take Control Agent that could be exploited by a local unprivileged attacker to gain SYSTEM privileges. Tracked as CVE-2023-27470 (CVSS score: 8.8), the issue relates to a Time-of-Check to Time-of-Use (TOCTOU) race condition vulnerability, which, when successfully exploited, could be leveraged to delete arbitrary files on […]
A previously undetected attack method called NoFilter has been found to abuse the Windows Filtering Platform (WFP) to achieve privilege escalation in the Windows operating system. “If an attacker has the ability to execute code with admin privilege and the target is to perform LSASS Shtinkering, these privileges are not enough,” Ron Ben Yizhak, a […]

Privilege escalation attacks pose a severe cyber security risk to all kinds of systems in public and private organizations. In these attacks, threat actors exploit vulnerabilities or design flaws in operating systems and software applications to gain illegitimate access to resources that would otherwise be restricted to authorized users only, triggering dangerous hacking scenarios. As […]
